The Ambassador body, which I’ve not been able to find any info on, came in a box of parts pens. I thought it looked neat. The steel nib wasn’t salvageable, but the rest was in great condition, and a spare Waterman #2 left oblique nib fit perfectly. I did have to substantially deepen and expand the feed’s channels, but after the ebonite dust cleared I had myself a wonderful little pen that I dubbed the Ambassador 52. I consider it to be like a “sleeper” car; it looks cheap until you get in on that long Rhodia highway to stretch its legs tines.
